Still testing the hardware rendering option of the OpenDX 413 Windows version with WindowsXP and an Nvidia Geforce2 graphic card.

WinaXe color depth can be set to 8, 16 or 24 bits or to "auto" . If it is set to "auto" it is adapted to the desktop dcolor depth but with a maximum of 24 bits. But my PC allows a choice only between 16 bits and 32 bits colors (resriction due to Windows XP or to my graphic card ?). So the only possible choice for color depth compatibility would be 16 bits, but in this case OpenDX does not give acces to the menu for switching between hardware and software.

In the settings I found only a choice for PseudoColor mode that I set to off and I kept my desktop in 32 bits colors. I set also GLX buffering on. Hardware rendering fails again. Here is the response of the Starnet support : > >I do believe the hardware rendering problem running >>OPenDX is actually on OpenDX itself, according to OpenDX >>developer I talked to awhile back. You might want to contact >>them for the solution. So who is right? Is it an OpenDX problem, an X-server problem, or a compatiblity problem between desktop color depth and X server color depth? Any suggestion would be welcome.
